SpaceX Stock Faces Post-IPO Valuation Risks as AST SpaceMobile, Rocket Lab Rebound

SpaceX stock has surged from $135 to over $225 post-IPO, pushing the company's valuation to $2.5 trillion—a move driven by retail options activity and limited float rather than underlying fundamentals, according to Investing.com. The aerospace company trades at 20x projected 2027 sales while recording $4.94 billion in annual losses.

The valuation expansion comes amid a $60 billion all-stock acquisition of Cursor and ongoing Tesla merger speculation, both of which continue to inflate the stock price. The steep multiple and massive losses present substantial downside risk if retail momentum fades or float increases.

Meanwhile, AST SpaceMobile and Rocket Lab have been temporarily overshadowed by the SpaceX IPO frenzy but now offer more attractive risk-reward profiles at current levels. Both space sector plays have rebounded as investors reassess valuations following the SpaceX run-up.
